How does volume work with FXCM?

[NinjaCustomer]

if I make a 100 tick chart on FXCM forex data.. it will show different volume bars for each 100 tick bar.

If I use Sierra Chart which has FXCM data also, every single 100 tick bar will have the exact same volume.

Since ticks are used as a proxy for volume, why is volume not the same for every single 100 tick bar in NT?

Hello ,

Thank you for your post. This is expected due due the time stamp of the tick data and different times data is loaded. As a tick based chart is open, the most current bar begins building at that time.

This means that if the chart is opened or refreshed after the session has already started, these charts will be different than the historical data that is downloaded which will include the data from the beginning of the session without a new bar forming where the chart was opened.

In other words, if you open a chart before the start of the session and never reload this, this would match the historical data. See the below section of our help guide for more on this matter, "Understanding why a chart can look different after reloading historical data from the server."
